Headers and IDs .. automated?

Question

Hello, this is my first time here and I need some help in creating a Tool/Addon/Extension. My group and I are currently marking up a large number of tables to be accessible and compliant with CLF/508. For short/small tables, it is not a big deal but when dealing with huge tables (think a few pages long), it is very time consuming to associate every cell with a particular header(s) one by one (especially with 4-5 headers and sub-headers) when we can't use the scope attribute.
The plan is to have a tool to select multiple cells and to add a particular header to a whole row or column in one action. Since there are more than one header per cell, it would need to be able to append whatever is there also. I was hoping I could build an extension or possibly make another Property Inspector. I was thinking that for a Property Inspector, adding a "Headers" (attrib) field (it is not in the Property inspector.. but it is in the Tag  inspector), and then populating the Headers combobox with whatever TH IDs that are already defined in the table.. and simply appending the selection of the combo (or click an "Add" button)
Is the Property Inspector capable of handling something like this? Dynamic combobox (updated using defined IDs..) constantly updating.
Is there is an easier way to do this? Even if it means writing out the Header IDs manually in a text box and then "Add", would still save a lot of time.
Is there an example of something like this where you can change/append one attribute in several similar selected tags? I know you can apply styles for example but I would love to be able to have it similar where all the IDs (from TH) are listed in a listbox/combo and can simply be selected and applied to a bunch of cells.
Thanks so much!
