Plugin Suggestion for Discount when 2 different specific products in cart

I have been trying to find a plug-in that fits my needs but I can’t seem to find any that do exactly what I want.

I run a clothing brand e-commerce store and I am trying to set it up so that a specific category (2 T-shirt’s for $35) will automatically discount the total price in the cart when 2 shirts are added from just that category.

Example:

Shirt #1 = $20 on its own
Shirt #2 = $20 on its own

Add Shirt #1 & #2 to cart and instead of the total being $40, a discount is automatically applied so that it becomes $35. But I want it to only happen when it’s 2 different products from that one specific category. It can be any 2 products from that category as it has about 75 different shirts in it.

Can anyone recommend a good plugin to achieve this feature?

Thank you in advance!!!
