Page/Post Edit – Add Custom Menu

Hi,

I am using custom fields quite extensively but was hoping I could have a custom menu, derived from the “Custom Fields” menu that just use certain fields

Basically I have some options/fields for “Twitter, Facebook, MySpace, Last.fm, Probability and Times”.

SO rather than someone selecting the option from the dropdown, adding a value and then clicking on “Add Custom Field” (as they do currently), I would ideally have a menu in the right hand column (Under “Tags”?) that has these fields listed with a blank text field text to them. The user can just easily paste/write into these boxes and it’ll work like the “Custom Fields” menu currently does

Make sense? Anyone push me in the right direction?

Thanks!

JJ
