Question: Solutions of a PDE system / rifsimp

Does the current implementation of Maple has any any command to characterize the solution of a linear PDE system with m unknows (functions) and n variables?

I need a command that receives as input the PDE system and tells the nature of the solutions: k0 constants, k1 functions of 1 variable, k2 functions of 2 variables, ... , kn functions of n variables. I think mathematicians call this the Cartan character of the system (I am an economist).

I was reading and re-reading the manual for rifsimp but it could not find anything there.

There is an Maple package I found online (Janet) that does that but it is too sluggish, I was wondering if there is a more efficient alternative. Thanks,
