How can we add Building Slots

[sgtkatharn]

From what I have found it looks like the building slots run off a template, campaign_map_settlements_template->sho_generic_castle (I found it in the Assembly Kit) but you can't export the table to put it in a mod. It also looks like that the different settlement types have a +/- to the base slot number from the template eg. capitals have a +2 and minor settlements -2 to give the relevent number of slots.
I have tried changing the values in this table
db->campaign_map_settlements_tables->campaign_map_settlements
as it has slot_count modifier as well as slot_type both these have the values of 4 and settlement respectfully which led me to my +/- supposition, does anyone else have ideas on this. It would be good if we can crack this

I don't think that particular number is used for anything (although it does coincide with the number of secondary slots for a walled settlement). The primary and port slots would have to be considered completely seperately (which makes little sense), nevermind how unwalled settlements only get 2 secondary slots.

As for what does control them, I have no idea.
