Ability to Copy Mail Messages to Multiple Mailboxes, not just Move a Message to one Mailbox

Need to be able to COPY mail message to other folders (labels) on iOS, ie Phone and iPad. In the Mail for Mac OS I can do it no problem. But in the iOS version of Mail there is ONLY an option to Move, not COPY a message. This is essential to do any sort of tasking where users like me use labels (many more folders/labels than just “inbox and trash”). This is essential for people who organize their inbox and need to segregate certain messages into 2 mailboxes (labels). Please help! I like the native Apple Mail interface but cannot use it and have to do Gmail because they natively permit the assigning the message to more than 1 folder/label/mailbox.
