How to translate package easy with dynamic name

Installation Home Assistant OS
1

I’d like to translate a package script called my_script_package.

I created a file called languages.yaml inside packages/my_script_package:

input_text:
 
  lang_used:
    initial: IT
    # change this to change languages: IT, UK, FR, DE, ....
 
  ################ TRANSLATIONS ################

  lang_string1_UK:
    initial: English string
  lang_string1_IT:
    initial: Stringa italiana
  # ant others langs...

I’d like to change names of other entities based on value set on lang_used

For example, inside packages/my_script_package i have a file called variables.yaml:

input_boolean:
    
  string1:
    name: English string
    # i'd like it to be dynamic based on lang_used value.

My goal is to set name variable but i don’t know the correct syntax.
Something like:

 string1:
   name: {input_text.lang_string1_{{ states(input_text.lang_used) }} }

Anyone has a good idea for this?
