Hello, is there a way I can make the second product variation to calculate percentage of the first product variation and not to the base?
For example, I have a base price of 2, and variations
1. Medium - modification 0
2. Large - modification +5
3. XLarge - modification +6
and second variation
1. White - modification 0
2. black - modification 0
3. Red - modification +10%
If I chose product Large / Red it calculates: 2+5+ (10% of 2)= 7.2 and not 2+5+10% = 7.7.
It there an addon to make it like this or an option?
Thank you!
