linked to cooltime?

hello, my main language is not eng, so it could be weird sry
 

is there a cooltime linkage function between store ("a" and "b")?

If im buy "a", the same cool time applies to "b"!

Hi. Try to rephrase or post what you wanted to convey in your own language.

I would like to link the cool time of the items "a" and "b" registered in the store.
