Align to Guideline?

Hi guys, I set global guidelines to position hyphen, enspace etc. maths symbols, .case and then position these manually. But was wondering if there is a way to set a guideline, give it a name and then select specific glyphs and align to the centre of that named guideline? not sure if something like this already exists?

At the moment, there is no centre-align with a guide. There are two plug-ins that display center lines though: Show Smart Plumblines and Show Center Lines. You could check and see if the center lines coincide with the guide.
