When we treat the fields of the form booking shown in step 1

I had too much work to rearrange the order of the fields, it would be possible to implement something that would facilitate making this order in own list of fields?

how to order menu items, articles, categories, or modules in joomla
this exmplo can drag the item to positions above or below.

Or even how one orders the fields in Community Builder that in no way own list of fields to assign an order number to each item and apply that order.

Any of these two forms of ordering are much more productive than the current where we need to enter the issue each intem individually to assign you an order number
