[Help] org-capture: How to capitalize the text entered from the "nth prompt"

[Maske]

Hi

Could it be possible, in org-capture, to capitalize the text entered from a previous prompt?

Example:

I have this part of an org-capture template:

 
* %^{CLIENT} _%^{Project}_ /%^{Description}/
:PROPERTIES:
:DIR: z:/! 2023/%\\1-%\\2-%\\3
:END:

I would like to know if it is possible to “capitalize” the used data that I entered before. For example, instead of this:

** Client _Project Number_ /Project description/
:PROPERTIES:
:DIR: z:/! 2023/Client-Project Number-Project description
:END:

Could it be possible to get this? (The 3rd line is “capitalized”):

** Client _Project Number_ /Project description/
:PROPERTIES:
:DIR: z:/! 2023/CLIENT-PROJECT NUMBER-PROJECT DESCRIPTION
:END:

Best regards
