Making a namespace sortable and changing a namespace into another

[UnlimitedArk]

Hello, I had two questions,
first one, how do i make a specific namespace sortable ? It seems to be random and I didn't find anything in the settings
I used to have 'Timestamp' as a sortable namespace but it up and disappeared, now i have no way of sorting by release order, 'Date' goes by added order which is another thing entirely, other namespace get added randomly in the list as well

second, is there a way to change a namespace into another?
I've got lots of entries that have 'Date_released' instead of 'Timestamp', i'd like to change either one to the other if possible.

• You can sort by a namespace as soon as it's present more than once in your dataset; The dataset is built using the stats API though, which can exclude namespaces you add in settings since Implement excluded namespace logic #1471. Maybe you added timestamp over there by mistake?
• You can use tag rules to create a rule that converts date_released to timestamp, then use batch operations to apply it to every relevant entry.
