Your solution is correct. Each incrementer can be assigned an interval, but that value must be an explicit integer. That means you'll need two separate portals if you want one with an increment of one and another with an increment of two.
The other approach you might consider is to always use an increment of one and then setup the multiplier internally. For example, if you look at the Savage Worlds example files, they use a range of 2-6 with an increment of 1, then they multiply everything by 2 for final display. The user sees it as a range of 4-12 with an increment of 2, but it's actually tracked as a range of 2-6 internally.
