Addition Program Arguments when running in debug

So, I am currently trying to set up a development environment for a somewhat weird platform. The built executable cannot be executed by itself and instead relies on a external executable it is then passed to. That executable has additional debug arguments when one wishes to debug.
In that sense, I have two questions.

1. Is it possible to add additional program arguments for when the run config is started as a debug run?
2. Is it possible to automaticially attach CLion's gdb client to the server that the external executable starts?

Thank you for all upcoming responses.
