Thanks for the reply and the assistance. Basically that is what I want achieve, but I'm hoping to do it within the confines of a single voice - note the dotted half note F above the phrase in my original example, this whole thing is played by the left hand. Your reply did spur me to solve the issue in a fashion by having a 3rd voice and merging all 3.
However, this doesn't quite take care of the overall issue. It's a workaround I'll obviously just embrace for the moment, but I'd really love to not have to split passages into multiple voices and then merge them just for the sake of a couple ties. I have a lot of phrases where a single note is tied to one note an adjacent chord - is there really not a way to achieve that without breaking every such instance into multiple voices when the texture isn't really a contrapuntal situation?
At any rate, that did get me out of that snag, so thanks v much, o_e.
