U1 Multi-material; support interface layer

Software Snapmaker Orca
1

Hi,

I want to print in PETG with PLA as support.

Selected PLA for Support/raft interface and PETG as Support/raft base.

Works fine for the interface at the top of the supports (overhangs)

BUT: If I need a support that is growing from the model (not from build plate) itself that interface-layer is not printed in PLA but in PETG.

I would have expected that this interface layer is also seen as interface layer and therefore also printed in PLA….

Have I missed a setting?
