There is not... the way a pool of fee operates is fundamentally different than how diesel pools work. Diesel pools do not have LP tokens that you get when adding liquidity and lp tokens represent a portion of the pool and that can go up in value from what you input into the pool
Diesel pools are not able to put fee tokens back into the pool... so they have to think in a different way. I imagine their technical limitations produced the fee-less system of diesel pools and I bet they wanted to do a fee system but couldn't figure out a way to do it without eth/bsc type smart contracts and an lp token system that seems pretty complicated and took uniswap and others a lot of careful planning.

Therefore a system where pool creators decide their own reward mechanism seems more doable and easier given their system and hives ability to send feeless transactions as opposed to other chains where there is a burden of cost for transactions and you leave that burden to the end user
