I want to catch results of custom psexecute commands generated by Subscriber command transformation policies.

I want to add cusotm operation data to those commands that i generate and I want to catch the status of the those commands including
operation data that was submitted initially with request:

command example:

<nds dtdversion="4.0" ndsversion="8.x">
<product edition="Advanced" version="">DirXML</product>
<contact>NetIQ Corporation</contact>
<modify class-name="User" qualified-src-dn="{usercontext}" src-dn="{usercontext}" src-entry-id="34152">
<modify-attr attr-name="psexecute">
<value type="string">Set-Mailbox -Identity "{usercontext}" -CustomAttribute4 "bingo!"</value>

commadn output

<nds dtdversion="2.0" ndsversion="8.x">
<product build="20170326_1258" instance="Azure AD" version="">Identity Manager Driver for Azure AD and Office 365</product>
<contact>NetIQ Corporation</contact>
<status event-id="0" level="success"/>

How to add cutstom operation to data to that comamnd and catch the status and with its operation data??

My rule on the subscriber command transformaiton looks like this:

<description>Test of psexecute</description>
<if-class-name mode="nocase" op="equal">User</if-class-name>
<do-set-dest-attr-value direct="true" name="psexecute">
<arg-value type="string">
<token-text xml:space="preserve">Set-Mailbox -Identity "{usercontext}" -CustomAttribute4 "bingo!"</token-text>
