Parallel voices with different time signature and same compas duration.

I'm composing with rhythm modulation techniques that need to be able to write two or more voices with different time signatures, for example: 11/8 & 7/8
It's important to be able to keep compas duration joined, in the sense that 11/8 of one voice last the same time than 7/8 of the other.
Is it posible to do this in musescore2 already? I haven't been able to find how.
Could this be implemented in near future?
Any guidance would be very appreciated.
Thank you all for this awesome software and community!
