Allow overriding sessions name

[xeruf]

Is your feature request related to a problem? Please describe.
I would like to have a shell alias that presets a session name but can still override it

Describe the solution you'd like
when multiple session names are provided, aichat maybe spits out a warning instead of an error but then goes with the last session name given

Describe alternatives you've considered
writing a shell function, but that makes it a bit verbose

I don't understand what you are talking about. Can you give an example?
