PowerShell Batch Edit question

Can the "Edit - Special Action > PowerShell Command" be used to modify the properties of a folder connection type?

I'm trying to edit / remove the highlighted property from a number of folders that it has been set.

<?xml version="1.0"?>
<ArrayOfConnection>
<Connection>
<ColorMode>Inherited</ColorMode>
<ConnectionType>Group</ConnectionType>
<CreatedBy>ACOMPUTER\user</CreatedBy>
<CreationDateTime>2023-07-06T23:44:15</CreationDateTime>
<CredentialConnectionID>B87B29D9-9239-4D7B-86D8-9B53DCD3BA9F</CredentialConnectionID>
<Group>test</Group>
<ID>dd72c0cf-d863-426f-af41-1278c4c5b40f</ID>
<Name>test</Name>
<TabGroupMode>Inherited</TabGroupMode>
<TemplateSourceID>55416a52-8373-4420-b324-7ace19288076</TemplateSourceID>
<UpdateDateTime>2023-07-06T23:44:40</UpdateDateTime>
<UpdatedBy>WINDOWS10\Connetic</UpdatedBy>
<GroupDetails>
<DefaultAction>CopyPassword</DefaultAction>
</GroupDetails>
</Connection>
</ArrayOfConnection>

I attempted:
$connection.GroupDetails.DefaultAction = "";
$RDM.Save();

But it doesnt work, in fact I tried some basic changes to even the name and it only seems to affect all of the sessions contained within.

Thanks in advance!
