Is there any way to configure the NAL workstation components to ignore
application objects that don't have distribution rules?

Scenario: Existing ZEN2 environment with old clients, NAL and old
application objects. Rolling workstation upgrade project with new images,
using ZDM65 imaging and ZFDAgent. 'New' application objects for the
re-imaged workstations. Want to prevent the 'old' applications (which
won't have distribution rules) from deploying to new workstations without
having to add 'legacy' System Requirements to each of the old apps...

Any suggestions?!

Many thanks
