Appogiatura before the bar line?

I've been using MuseScore for about a month. It's a great program!

Mainly I transcribe baroque sonatas. In some, appogiaturas come before the bar line. (See attached png file). I've tried to copy this effect but the work around is tedious and ineffectual. Here's what I did:

• Select a note - [Create] - [Symbol] - insert quaver
• [Create] - [Symbol] - insert tenuto I had to do this twice to create the ledger line effect
• Select the G4 crotchet - add slur
• Reposition the slur to fit the appogiatura
• Fiddle with the G4's Note Properties to make sure that the spacing is acceptable

[See attached MuseScore file]

I'm not happy with the finished result because the note head on the appogiatura is too big. The other workings I can deal with as the effect doesn't come too often.
