Is your feature request related to a problem? Please describe.
When it comes to diagramming (data architecture, modelling, etc.), I usually work with them in two ways and I wonder if there's a way to achieve it in draw.io. Let's assume 3 phases and there are things that are common between phases and things that change.

*** First approach ***

• each phase contain all common parts, let's say elements A, B, C
• each phase adds the components that appear later
• I keep all layers visible, ordered from the last phase at the top.

This way if I disable Phase III, it shows Phase II, and so on.

Problem: It only works when I add components in new phase but not when I have to remove it

*** Second approach ***
Copy everything between layers and remove/add.

Keep only one layer visible at the time.

Problem: I need to keep switching and adding common components to all the layers. Plus when presenting I need to hide and then show new layer.

Describe the solution you'd like
I haven't found any documentation whether it's possible to streamline the layers' behaviours. I would like to be able to have settings per component and perhaps make it unvisible on a specific layer.

Settings per component could work with a default all "visible on all layers".

Describe alternatives you've considered
I use the first approach and just tell people things will not exist at specific stage.

Additional context
I think the shift would be from a component "belonging" to a layer to "visibility in a layer".
