working with channels - DTP white channel

[dreake555]

Hello!

 

I've just started using Affinity Photo on windows, and it's look promising although i can't figure out one thing. Is it possible to add other channels to work with? I'm mostly using PS to prepare files for DTG printer, where I need to create channel that represents white ink. In AP eg. when working with CMYK, there are only Cyan, Magenta, Yellow and Black channels, and I can't add my own (or i don't know how). Anyont can help me?

Thanks :)
