Release dates can be specified by store or a deliver cancelled to a certain store altogether by using the "Schedule" tool.
To access the tool, go to Release Management -> Release List -> Select the release you wish to edit -> Click "Schedule" in the icon menu.
If you do not see this option on your account, please email Label Worx Support
Here you will be able to select a specific date separate to the official date you set, or cancel a delivery to a store altogether. You also have pre-defined quick set options at the top.
There are some rules to keep your label in good standing with the stores though, do not set a release date on a store, during any exclusive period you set on another store. Unless the release is a variation of the original product, i.e. Radio Edits being sent to the streaming platforms.
For example if you set a Beatport 2 weeks exclusive on 01/05/2016, do not set the release date on any other store until after the exclusive period finished on Beatport. If you don’t set an exclusive period, you can pretty much set it as you wish.
