I doubt that UMDK has support for PS' bank-switcher.  It was a pretty large, custom cartridge.

And is it possible to add own bank-switching?

The bank-switching is documented here: https://github.com/makestuff/umdkv2/wiki/Internals#ssf2-banking

It works by introducing a logical-to-physical mapping into the memory-controller: https://github.com/makestuff/umdkv2/blob/20170319/vhdl/mem-arbiter/mem_arbiter.vhdl#L206-L210

So, yes, any conceivable bank-switch mechanism is achievable, but the default one is IMHO good enough for any MegaDrive game. I suspect the only reason Pier Solar uses a nonstandard mechanism is for copy-protection reasons.
