We use a custom field to tag projects with our purchase order numbers. Our purchase ordering system allows and often includes leading zeroes, however Wrike removes those upon submission. I didn't see an option to allow them in the custom field's options or any other posts w/ a similar feature request, but I can imagine there are a few other places where it would be nice to have, invoicing systems might use leading 0s too. It's not a huge problem, but it would be nice to be able to enable them.
