Question on estimated time to completion

Currently running SKR with Marlin, but have a jackpot board sitting in the box waiting for me to play with it.

Running the machine with Repetier and USB connection I get an estimated time to completion. I have recently upgraded the SKR with the ESP01S for wifi, but ESP3D-UI only has a progress bar with percentage no estimated time to completion.

My question is has anyone implemented a timer function for FLUID, or anything like it already out there?
