There is a great ACF extension plugin ACF Quickedit Fields https://wordpress.org/plugins/acf-quickedit-fields/
The problem is, that it seems to be abandoned. It would be great, if this function would be incorporated into ACF (Pro), i think users would love it.
The developers of ACF don’t generally watch these forums. You should send them your feature request by contacting them or submitting a ticket on your account if you have a Pro License.
