Open Could anyone write a procedure for me against payment?

Hi, I am very new to Tasker and AutoInput. I know that sooner or later I would get the hang of it by fiddling around, but would like to save some time. So my question is: could anybody make this happen and send me the xml file against payment?

I use TypeApp for my emails. when I answer to a message it starts the quoted text with "On 16 Apr 2019, at ...... wrote:"

I wanna replace this text with something else as soon as I open the "reply"-screen.
