Way to automatically create a step for a given worker based on conditions?

Hi all!

I'm a relatively recent addition to the Tessitura community (hired with the SDSO at the beginning of December) but I'm learning so much and having so much fun.

In my position, one of my responsibilities is personally thanking donors in a certain amount range, whether by phone, mailed note, email, etc. I know that you can create certain acknowledgement letters to go through automatically, and right now we have that set up for the tax letter, but what I'm doing are more personalized, less formal letters. So if I need to contact anyone who donates between $500 and $15,000 to our annual fund, is there a way to create a function that automatically creates a step for me if someone donates in that amount range?
