Of course! So here is a sample from the real thing:
Actually it is not only with the grace notes before barline that this occurs, it is with all grace notes and not consistent. No player would misunderstand the notation, but it does look better with the correct trill line length:
This one is adjusted with manual note spacing in engrave mode. Sometimes it is possible to adjust lengths of the trill lines in Write mode, but then extra space is added and other complications arise. As you see I did not even succeed very well here, the 2nd and 3rd bar are not yet as the should. Another way would be to increase spacing and split the system in two.
