Question about ARA integration with using multiple ARA extensions on top of it

Hi

i have question regarding the ARA Extensions.
Lets say, i have an audio track, first i´m going to apply SpectraLayers One and removing some noise, generating layers with different volumes, etc
when i double click on the event, SpectraLayers is going to open again and i see all the layers and can make again adjustments, perfect.

then i want to apply Melodyne via ARA, Melodyne opens up, i can do all the corrections, great

BUT what if i want to make a some adjustment on the first SpectraLayers One Instance? how can i do that?

thank you very much
Chris
