Enable Unit recruitment locally in individual towns in addition to the regional capital?

[Taraphir]

Scince modifying the campaign map becomes possible it would be a nice interim solution to enable unit recruitment at the local level of individual towns in addition to the regional capital. This could be a way to compensate for the negative side effects of the present size and number of provinces in Empire Total War. A method of that sort could be most helpful to prevent blitz attacks to some degree and bestow more relevance to smaller regional settlements. Imagine for example town watch units with zero action points(no movement on the campaign map allowed) that would be forced to defend their home settlement because they couldn´t move at all on the campaign map. I attempted to incorporate this reruitment scheme into the game by modifying the db files unsuccessfully and therefore presume that something has to be done in the startpos.esf to achieve results. Can anybody give me some advice please!
