Conditional Fields - further conditions

Heya, 

Heres my context for example: 

Game A has Feature 1 and Feature 2

Game B only has Feature 1

I have only one Ticket Field for Feature. I want to avoid creating multiple Ticket Fields for Feature, as it's messy within Explore and in Ticket Views. 

So using Conditional Fields - When user selects Game B and then they select Feature 2, I want text/notice to appear that 'Game B does not support Feature 2, please select another option' and to disable the ability to click Submit.

Is that possible in Zendesk or will I need a developer to create custom code? 

If custom code is needed, is there a space here on Zendesk where we can reach out to developers? 

Thanks in advance,

Mitch
