If you can dynamically populate the link the user clicks on in the third party tool then yes, you can pre-populate your dashboard by making your link look like the code below.
[URL]?form.[target_token_name]=[$source_value$]
[URL] = the URL of your Splunk dashboard
[target_token_name] = the name of your Splunk dashboard token
[$source_value$] = the value populated from the third party tool.
