multipart/form-data on scripting tool

Hello friends,
I need to replicate one information from the request, that is in a part of the multipart/form-data body, on the response. I would like to know how do I refere to specific part of multipart/form-data on the scripting tool.

Below is the request:

POST /api/v1/liter/application HTTP/1.1
accept: application/json
content-type: multipart/form-data; boundary=BoundaryAthenaabcdefghijklmnopqrstuvwxyz
user-agent: Athena
host: testserver.com
content-length: 441
cache-control: no-cache

--BoundaryAthenaabcdefghijklmnopqrstuvwxyz
Content-Disposition: form-data; name="software_options"

5:262144:24
--BoundaryAthenaabcdefghijklmnopqrstuvwxyz
Content-Disposition: form-data; name="info_rtc"

2025-03-13 13:28:58
--BoundaryAthenaabcdefghijklmnopqrstuvwxyz
Content-Disposition: form-data; name="apitoken"

ZDLJD3CSSKF29F0FLFJBL1994082741880DFS03044K3AZJ1135B29C825009344
--BoundaryAthenaabcdefghijklmnopqrstuvwxyz--

I need to get the date "2025-03-13 13:28:58" and put into a global variable to use it in the response.
I would be very grateful if someone could help me.
