Reserving item numbers; Turning off certain listings

[cbradiospronto]

Two topics but related in my case:

When goin on vacation, I would like to continue to list items that my dealers drop-ship for me.  However, I don't want my other listings active since I'm not home to prepare them for shipping.  If I simply end some of the listings, I lose the item number associated with the listing as a new one will be assigned when relisting.  This is a problem because, within my listings, I have specific links to other items in my store.  Changing all the links to the new listing number will take dozens of hours of work, at lease.  Here's and example of one of my lisings. ebay.com/itm/140676786786

Any sugestions, outside of putting my store on vacation and listing the items on another eBay account?
