URL Filters and Custom Link Filters

I realize that the domains you set in your admin URL Filters, and Custom Link Filters in the s_code can be different, but the typical implementation is that these should be identical.

Could you allow us the option to set in the s_code that linkinternalfilters=URL filters? this way if I make a change in the Admin tools, I'd automatically update the link filters without needing IT to change my s_code.
