Is there a way to "remember" the search values of column range filters? (similar to aoPreSearchCols)

Hi

Im my plugin YADCF I want to be able to support the bStateSave for my column filters, I know I can use the aoPreSearchCols to load the filters values for my simple filters select/autocomplete, but the more advanced filters range_number/range_date/etc... works a bit differently from the simple ones and because of that their values are not being stored in the aoPreSearchCols (for a good reason) but still before I'll start writing my own cookies I wanted be sure that there is no other way to do it with the help of datatables.

So is there a way to store the range filters values (from - to) with datatables, or I must add my own cookies?

Daniel.
