IOS App - Accounts & Category selector - Search Fields

Please can you consider pinning the search fields within the IOS app (might apply to the Android app as well, I do not use it) to the top of the screen, so that when a user is looking for a description, category, account etc. they do not have to scroll to the top of screen to do a search... I believe that the app selects the last used description, category or account when fields are clicked into.
