Collections of designs instead of single products - Printful

[Lory_CarFace]

Hello everyone, I'm new to Shopify! 

I'm a graphic designer and I started this adventure to make a living out of my art, using Printful for dropshipping. 

I'm using collections to split my designs by theme, and it's a great way to organize the storefront. However, I'd like to make 3 products for every design (unisex t-shirt, female t-shirt and a poster) but since there are hundreds of designs and a dozen of collections, it would be a mess to triple the collections to have a separate one for every product type. 

Is there a way I could organize my store making people browse collections of designs, select the design they're interested in and THEN select the type of product they'd want it to be applied? 

Sorry for my bad English, I hope I was clear enough. Thanks in advance for the answers.

Sorry if i'm bumping the thread but I haven't found a solution yet. Any idea?
