What do you mean?
1] To be re-researched later, under a specific condition? if so then yes, but you must use the code I used for Ahriman in Thousand Sons. WARNING: You must not change the values, because you will have CTDs. The method I used there is never used before, and you must know EXACTLY what you are doing - it is as complex as AE can get.
2] OR to be like an ability? If so,.... use an ability!! Buildings can also have abilities
Thank you very much brother,i think the ability is exactly what i need
