We need milisecond adjustment option for Nano Cortex delays

Hello everyone. Forgive me if we have this and I could not find it.
We seem to only have BPM option for delay time for Nano Cortex.
Can we have milisecond type adjustment as well so we can choose?

Only BPM makes it really hard to fine tune slap back delays.
All of the delay pedals manufactured so far has this UI detail so please add it to Nano. Thanks
