Could you implement a function that I consider very important?

I would like for example when I run an LLD that returns {#PROCESS_NAME} and {#PROCESS_USED_MEM} on the discovery and prototype I can create an item with the process name using {#PROCESS_NAME} and the value that is collected is {# PROCESS_USED_MEM}, I already made several LLDs where I can collect everything I need in msm json, but I need to save the output of json and use a jquery or own script to execute and be collected in zabbix, could implement this function, where in the prototype item I pointed out that the value to be collected was the return of the LLD macro itself? Thank you
