Any way to use seconds in the Cascade Curve Editor? (4.27)

Tried making a particle with an infinite lifetime, but I have come across an issue.

See, the Curve Editor in Cascade’s Particle System uses a system of 0.0 being the start of the particle lifetime and 1.0 being the end of the particle lifetime. You can sort of see why this wouldn’t work with a particle of infinite lifetime.

So, my question is: is there any way to use seconds in the Cascade Curve Editor in 4.27?
