I'm newbie to Resolume so may be this is a silly question, sorry in advanced

Well I have this big composition with dozens of layers and I'm using several Layer Routers to create controlled and independent feedback loops among different clusters of layers.
So far so good all works as expected.

The problem comes when I want to modify the composition's structure for example adding a new layer.
After adding one layer, all the Layer Routers changes it's inputs.
It seems that they don't point to a layer, but to a layer position.

So the question would be:
What I'm doing wrong and how can I modify the composition structure (adding, deleting, reordering layers),without having to manual re-assing all my layer-router's inputs?
Thanks for your support!
