Hello,  I really hope someone can help me please.  I have over 40 pages of music for the Prefaces for church - each page being one separate entity for a special Sunday of the year.  I have bunched together too many measures on one line on page 3 of my score.  I would like to fit the last measure of the squashed mess to a system of its own, so that the following line of music (with the next paragraph of lyrics) can start a new system.  Everything gets shunted onto the next system when I try this, all systems being numbered in Finale.  The corresponding page layout measurements are causing havoc with the rest of the score. Please could anyone tell me if there is a way to insert a new system, whilst letting existing systems keep their measurements?  I am using Mac El Capitan.

Thank you,

Chloe
