Modify the powershell script to add additional parameter - powershell

Question

the below script was created by our pervious IT guy, what this script does is basically replaces the Funduc Software (RSP and RSBE) config file in the logged in user's Appdata so we can modify what the software will search over. E.g. Excel Word etc.
I need to modify this script in such a way that it when ran without any parameter provided it runs as it but if we specify a parameter it automatically runs the config we need.
Right now if we run .\RSUpdateConfigFile.ps1 it starts the script and waits for user to enter a number which corresponds to the extensions we need to search over, this works fine as is.
What we'd like it to do is if we run .\RSUpdateConfigFile.ps1 -L_V_1_String_PreSelection 10 it should execute the script and without prompting the user automatically update the config file with Word extensions.
Below is the code we are using. Any help or advice would be appreciated.

i added your parameter to the script, it should only prompt you when not provided:
