Create single bar lines without time signature

Hello !
I have a piece of music in which the bars are of very different lengths. Once 5 beats, once 3 or 2 beats, then again 4 beats etc., quite irregularly.
I would like to write this piece without time signatures (i.e. 3/4 or 4/4).
Instead, I would like to set the bar lines individually.
How can this be done (Dorico 4)?
Many thanks

Yes absolutely, you could create either no time signature or an open time signature at the beginning, then input barlines as and when you want them.

Great, thank you very much, I just didn’t know how to approach it exactly! Thank you! Now it worked!
