Yes, in JMP Live 18 more than one Local Data Filter filtering on continuous columns will be interactive.
I don't see how you can have two nominal Local Data Filters be active in JMP Live 17 unless you are considering a single Local Data Filter filtering on more than one nominal column as being more than one Local Data Filter. Here's an image of a dashboard with two Local Data Filters with nominal columns. The second Local Data Filter is not interactive in JMP Live 17.

I hope that helps clarify the limitation in JMP Live 17 and what to expect in JMP Live 18.
Please let me know if you have any further questions.
Thanks,
