Perk changing and skills

Hi.

I'm posting here because there is something (in my opinion) really badly designed regarding the perks. Let's suppose I play Support and I want to be a Field Medic.

So I go to the menu and I click Field Medic, so that at the end of the current wave, I'll use this perk. The issue is, I can't configure my skills at the same time, because when I click "Configure", it will always show me the skills of the perk I am currently using (in this example, Support).

When the wave is over I become a Field Medic, but the "Configure" Button is grey and I have to wait another wave to be able to change my skills. I don't know if this is intended or not, but it is really annoying.

It would be great if we could change perks and skills during the same shopping time.

Another thing I'd like to see is immediate detection of max ammo when you buy a weapon. At the moment, when I play Field Medic with "Enforcer : Enough focus on caring: Increase your starting ammo capacity by 20% for your Perk and Backup weapons", I have to buy a weapon, leave the trading window and use the pod again so that I can buy the max ammunition I can carry.

Thank you!
