Will DRIV be able to support multiple treatments via multiple instruments?

Hi,

From what I know is that for now DRIV and relative sub-estimators don't support multiple treatments and instruments. I wonder whether it is something under development. Moreover, specifically for my case, the treatments have one binary and one continuous variable, is it workable in theory by modifying the package codes by my own so that I can deal with both treatments together via multiple instruments? In addition, is there anything I need to take care or notice when doing this? Thank you so much!

Best,
Alyssa
