That's not currently supported. We need recurring revenue rather than one-offs, so that's what I'm pushing for right now. Out of interest, is recurring something you'd consider if there was another lower-priced individual tier added?
Totally understandable. I wouldn't just because my budget is very tight now.
Then don't sweat it! :)
I did fund your original kickstarter for DRF3 as a heavy DRF user at $job, and now might consider signing up as a recurring payment. Your code has saved me a lot of time and effort in my career, so thanks much sir!
