Automatic Availability Settings For Each Individual OTA

I would like to be able to set booking for 30 days out, Airbnb for 60 days out, and for example VRBO at 90 days out. While manipulating OTA’s for maximum revenue is difficult this is one step to automate a part of the process. I do not want to go into the ical for each channel and update it manually. Let me know if this is clear enough of an ask, or if I need to elaborate more.
