[Orgmode] Timestamp modifiers for specific tags

[Benjamin Tovar]

Hi,

I can specify a timestamp with a modifier like '-3m' to indicate that I
want to be reminded of the task 3 months before the deadline. Now, say I
have a tag :conference-deadline:, and I want all the entries with such
tag to automatically have the '-3m' modifier, without the need of adding
it manually to each of them.

 Does anybody have any pointers on how to do this? Thanks!
