For this case you will want to create a custom Vulnerability signature with a pattern match for string in the http-req-uri-path context.

I agree, accomplished similar blocks with this method

Thanks all.
For this case, would the following regex work?
.*Automated_Clearing_House_transaction.*
Which regex engine does PAN use so I can find a tester?
How do I apply this to a policy?

Regex is done in custom hardware, so it's not just a standard off-the-shelf engine, but for these purposes it's close enough to PCRE. In fact since you're just doing a string match simply using Automated_Clearing_House_transaction will work.
I created and tested a signature with the following config:
and it worked on a test url:
The XML for the signature is:
drogers@Captain.America# show threats vulnerability 42001 signature
<signature>
<standard>
<entry name="ACH">
<and-condition>
<entry name="And Condition 1">
<or-condition>
<entry name="Or Condition 1">
<operator>
<pattern-match>
<pattern>Automated_Clearing_House_transaction</pattern>
<context>http-req-uri-path</context>
<negate>no</negate>
</pattern-match>
</operator>
</entry>
</or-condition>
</entry>
</and-condition>
<order-free>no</order-free>
<scope>protocol-data-unit</scope>
</entry>
</standard>
</signature>
