how to make equally sized measures on all systems throughout a piece
The size of the measures depends highly on the number of notes in that measure, and as a result one system (staff) may contain 4 measures while the next has 5 and the last may have 3 widely spread measures.
Here, the min. distance between notes can be set and is a constant, while the size of the measure is variable according to the number of notes in it.
Is the reverse also possible?
... to set the size of a measure as a constant (or number of measures on a system), so that the distance between the notes is variable?
Example: It would be nice to have 4 equally sized measures on each system throughout the piece.
