Option to type slower in "type custom text"

I use this for software demo purposes, and I would love to have an option to type text a little slower, so it looks like it's being typed by a human.

I can do it today but it's a lot of work: Type "I", 0.3 second delay, type "would", 0.35 second delay, type "love", etc.

Thanks for your consideration.

+1 - I have a usecase where there is input lag to remote workspaces and chars get lost when typed "too fast".
