Right now, in the Security Detail View, specifically the "Security Details" box under the "My Holdings" box, we are given the name, symbol, type, category, and asset class information for the security.
The category information is only populated through downloading asset class information. It will persist for a time after you turn off downloads for the security, but once you validate your file, that information disappears and gets replaced by "N/A".
I'd like an option to persist this category even when downloads for the security are turned off as it provides some helpful information about the security, and potentially even manually fill in the category. I'd also like to be able to be able to sort by category in portfolio view. This is particularly helpful when you keep a watch list of securities you may buy in the future.
