Is there an equivalent to PS Apply Image?

Hi everyone,
I discovered Photoline one month ago and enjoyed it ever since.
I'm currently wrapping my head on how to reproduce in Photoline the techniques described by Dan Margulis on his PS books.
Many of them are easier done in PL than in PS! Sweet, sweet discover.

Except for one thing.
I have a portrait, and I would like to enhance the shape of the face. The standard technique in order to do this is:

• duplicate the current layer
• on the top layer, replace the blue channel with the green channel (using the "Change channels" command)
• on the top layer, apply curves to enhance contrast
• set the top layer to blend mode Luminosity

This is done effortlessly in PhotoLine: great!
Problem is: sometimes you don't want to replace a channel, you want to blend one channel into another. As an example, I would like to blend the green channel into the blue, in Lighten blend mode, with an opacity of the 80%. Doing so, I would replace the "shape" of the blue on the face, which is lighter in the green than on the blue, but not in the rest of the image, which is quite bluish.
This are things that, in PS, are done with the Apply Image command. In other softwares, I don't think it's possible.

Is there a way to achieve such a blend in Photoline?

Many thanks and congratulations for such a wonderful software.

You want to have 2 blends one after the other:
First blend the green channel with "lighten" into the blue channel,
Then blend this intermediate result with "luminance" into the background.

V1:
This can be done with groups that have the property "draw isolated". Once you enable it in the attributes of the group, layer modes are enabled for the group.
A normal group looks just good in the layer stack, but has no functionality. All layers in the group are calculated directly into the result from top to bottom, as if no group would exist.
An isolated group is like a picture of its own that starts with the bottom layer of the group. First all layers in the group are added to that, then the result is added to the whole picture.

V2:
Child layer. Drag the channel mixer onto the duplicate, and it just behaves like an automatic isolated group.

Both ways become tricky when you do everything with adjustment layers. It's still easy here, but at some point it becomes more easy to leave the non destructive way.

This. Is. Awesome.

I felt it was possible, now I think I must go back to the manual and study the capabilities of groups.
Thank you so much!
