Is your feature request related to a problem? Please describe.

Our team has successfully used the import CSV feature to create complex diagrams with over 100 elements including meta-data.

We often like to have the ability to use different layer visibility so certain items can be hidden, displayed during demo's.

Having extra import control over putting an element into a particular layer during the import process would save a lot of time manually doing this task post import.

The ability to change, and manipulate relative z-order as part of this may be useful as well (e.g from -10 lowest to +10 highest)

Describe the solution you'd like

The CSV syntax for import supports a 'layers' array with a named relative z-order and a column in the CSV can be mapped to the Layer name.

No layer id puts the element into the background default layer

#layername: layerId
# layers {\
# "Layer0" : "label="Layer 0;zOrder=10;",\
# "Layer1" : "label="Layer1;zOrder= 9;"}

Describe alternatives you've considered

As far as aware no alternative exists for assigning shapes to layers during CSV import.
