(disclaimer, I have very limited experience with / knowledge of this library, my apologies in advance).

You can do this:

command --intFlag 1 --stringFlag a --anotherIntFlag 2

And this works fine for simple cases. However, what if I have a complex cli structure, where you always need to provide a lot of options.

command --param1IntFlag 1 --param1StringFlag a --param1AnotherIntFlag 2 --param2IntFlag 1 --param2StringFlag a --param2AnotherIntFlag 2 --param3IntFlag 1 --param3StringFlag a --param3AnotherIntFlag 2 and so on for 10-20 parameters...

Rather verbose. The problem is of course the need for grouping per param, while the multi-values differ in type. Now if I'm understanding correctly, it's not possible to do the following:

command --param1 1 a 2 --param2 1 a 2 --param3 1 a 2

That's because for multi-value parameters, the value types should be the same and here we are mixing ints and strings. That is unless I define a custom type for each param that converts the combination of values. I'm I correct so far?

To work around this, I am actually working with multiple same-level subcommands to achieve this (since with commands, the individual values are converted rather than as a multi-value set):

command param1 1 a 2 param2 1 a 2 param3 1 a 2

This is possible, because I made every command a sub command of every other sub command, but this produces a rather complex command tree. What would make it a lot easier is if I could instruct picocli to allow for multiple sub commands on the same level, so that it would match any command on any level, prioritizing nested matches first (so A-with-sub-B B gets matched over A-with-sub-C B).

Thoughts? Can I solve this a better way already perhaps? I would be very happy to hear this is already possible in a clean way.
