How to Copy field to Layout v5.0.2

Hello everyone in this great community.
I have created a couple of of Layout Based Visit Forms for my practice. I would like to copy a custom field I created from one custom LBF to another.
I noticed that OpenEMR 7 has this feature when creating LBF but I am running OpenEMR 5.0.2 on a local Windows server (Windows 11 OS) with XAMPP v3.2.2 and the phpMyAdmin is v4.5.1 .

I would appreciate is someone showed me how to copy fields between custom LBF. I can find my way around basic functions of phpMyAdmin.
Thanks a lot.
