Backdoor Roth IRA: Can this be done incrementally in the same tax year?

Easiest: A one-time per year lump sum into brokerage until settled, then into tIRA, then same day to rIRA.

but...

Can I dump 1/26th of the annual amount into brokerage, wait until settled, then move to tIRA, then same day to rIRA, and do this after each deposit? (essentially a deposit after each paycheck, dollar-cost-averaging, if you will)....
