no way to extend buffs?

[shadowdrake14]

in an older version of the mod if you multiple chemicals on a sword the effects would stack(ie you could put 5 doses of cyanide on a sword and it would give it 5x the duration) is their a way to make a more potent version of the normal effects? in the current version 20 cyanide is the same as one and if i put cyanide and t-2 on a sword only the t-2 works. it would be cool if the sword added the buffs so that if you have 5 levels of cyanide it has 5x duration and if you add t-2 that increases the wither to wither VII etc.
ie more of a chemical adding duration and more powerful chemicals adding potency (or so they could get wither 3 and wither 5 at the same time for different durations)
