That's basically the only way to do it. Now, you can give measure of rest, instead of beats of rests, by capitalizing the rest. For example:

However, having a measure bar makes some sort of difference in LOTRO. I'm not sure what, but Z3 Z3 is not the same as Z3 | Z3, if I remember correctly (sorry, it's been a long time). So the best way to get every part to sync up is to make sure all the measure bars are the same -- just put in 12 lines of rests. Or experiment with Z instead. Let us know what works!
As a level 1 burglar, Bilbo got a pony when he joined the Smaug The Dragon raid. Then he asked for leadership, looted the chest, assigned himself the 1st age Arkenstone and mailed it to an alt (Bilbo's a VIP so can mail from anywhere). They did some PvMP and an Epic Battle, then he apologized and gave the Arkenstone back. He kept the pony.
