Charity donations - option for varying amounts#56

I really like the option to donate points to charity, but only having an option to donate one token at a time is rather time consuming if you want to donate more than once.

Would it be possible to add a feature to choose an amount so that you could donate 1 token, 5 tokens, 10 tokens or 20 tokens at a time please?

I’m ready to donate my point to tbay
