The displayPropertyKeys are already established as the visible entity names.
This provide the list of entities in the QueryAll page template, so your rule
definitely won't do as you hope.

The display keys inside the pull down are established in the
ERD2WQueryAnyField. I don't know if you can set a context for the relationship
in your rules. Worth looking into, I suppose.
keyList = relationshipContextDisplayAttributesKeys;
relationshipContext() - Method in class
com.webobjects.directtoweb.D2WQueryAnyField
This method is intentionally undocumented.
relationshipContextDisplayAttributesKeys() - Method in class
com.webobjects.directtoweb.D2WQueryAnyField
This method is intentionally undocumented.
I'm guessing no.

This rule works for a normal query page:
100 : propertyKey = 'summary' => qualifierOperators = ("contains")
[com.webobjects.directtoweb.Assignment]
For the queryall task you may want to try something like
task = queryall and propertyKey like '*' => qualifierOperators = ("like")
