I run into this issue daily, where I have several images that are stacked and every one of them has a circular mask. However, if I want words to be raised, I need to mask those letters on each image. This is painful, as I much apply the circular mask, and then a mask for each layer for each text. When using variables, this suddenly becomes a large effort. Could we get a group node that could contain a mask for all layers under it? Photoshop has really made this in an ideal way, and I miss that functionality here.
