I just tried and this is pretty easy to set up to have it all automated so you don’t have to manually move notes.
- Make sure you have your Page Template setup the way you want so you won’t have any overrides later on. Use the Default template for all pages.
- In Layout Options / Players, set the rests not to show. In LO / Page Setup, set the page number to show on the first page. In LO / Note Spacing, set the “only justify final system” to 1% to make sure it will fill the frame. In LO / Staves and Systems, set the Casting Off to 1 bar per system.
- In the first bar, input a time sig of 1/4, then Hide it in Properties.
- In Notation Options / Barlines, set whatever default barline type you want. I used a double bar here, but it probably doesn’t really matter.
- Input the quarter notes you want in each bar. (Obviously if you want half or whole notes, you just need to change the meter in step 3)
- Now there will be a bit of trial and error. Once you have everything set up the way you want, in Engraving Options / Spacing Gaps adjust the “#2 Minimum gap after barline” setting so your notehead is in the middle of the bar. This obviously will be dependent on all your other settings, but here’s what I used:

After all that, I have 3x5 flash cards with no overrides or manual moving of notes:
