Is this possible?

If I were to make a potion that (for example) raised attack speed by 10% for 30 seconds, is there a way to prevent another "speed potion" (example effect from test potion item file):

[EFFECT]
<STRING>NAME:ATTACKSPEEDUP
<STRING>ACTIVATION:DYNAMIC
<STRING>DURATION:30
<STRING>TYPE:PERCENT ATTACK SPEED
<FLOAT>MIN:10
<FLOAT>MAX:10
[/EFFECT]

from being used for 30 seconds so that it's not possible to stack the effects? What would I have to add, and where to, for this to work? Would I be better off trying to create a spell that does what I want then making a potion which, when used, has the effect of that spell? Thanks for any help.

There is a property "Exclusive" that you want to be true. This prevents stacking of effects, however i believe it will reset the duration to 30.

Note that this makes it unstackable with any effect with the same 'Name'

I'll have to remember that when I go back to work trying to figure that out, thanks for the info.
