Have weapons designated to specific keys

What I mean is having primary and secondary weapons relegated to the ‘1’ and ‘2’ keys or having each weapon category in it’s own designated slot; ie: ‘1’ for automatics, ‘2’ for shotguns, and ‘3’ for pistols.

I feel like these changes would help makes things a little less disorientating each round and can prevent sticky situations from happening if you’re not able to adapt to the constant layout swaps.
