Hello! I'm an intermediate Swahili student. I just discovered your channel. Very nice! Please keep up the good work.

Regarding this video, I assume you can also use this format in the conditional past tense, as we do in English?
Example:
I would have cooked whether they came or not.
Ningalipika wakikuja wasikuja.

(Or does it not work the same way in the past?)
