Multiple inputs in Formatting Map list

[Verilog]

Hi all,
Is it possible to directly add multiple inputs to Formatting map list directly without going to the popup and adding it manually?

For example :-
To add this list , it will be required to add it manually in each line.

1{|}List #1
2{|}List #2
3{|}List #3
4{|}List #4
5{|}List #5
6{|}List #6
7{|}List #7
8{|}List #8
9{|}List #9
10{|}List #10
11{|}List #11
12{|}List #12

I edited the textarea in html of that field to add this in one go but it doesn't store that data once I save that custom field.
Is there any other way to store this data in one go?
