You’re welcome! I have a suggestion and I hope it works. Maybe it will be possible if you use the find all and replace all in a text editor and search for <input id= and replace it with something like <input class="default-input-field" id= and then use the display: none for that class in particular.
However, I would like to ask you actually, would it be possible to copy the inserted id and use it in your custom input field but then delete the original inserted field?
