It is fiddly to send host data to multiple streams

[AlexHarker]

A situation where one wants to send one number from the host to each stream requires some additional patching that would be fiddly for.

See: https://framelib.discourse.group/t/multi-stream-slice-offsets/109/22

Also fl.tomax~ and fl.frommax~ (and equivalents in other languages) are somewhat asymmetric in their response to being forced into multi-stream operation (fl.frommax~ still only has one input). It might be that a (non-breaking) change would enhance the object set, or it may be that additional objects that target this specific issue would be helpful.
