Jar files in OSM generated Par files

Hey All-

Wanted to know, if there is a possible way NOT to package the OSM / Weblogic jar files during the generation of the cartridge Par file using Studio build option. Instead can we reference these from the server path?

The reason is currently our par files are up to 25mb in size and the deployments take forever. We also observe that the customizations constitute 3mb of the par file while the rest of it are libraries like coherence.jar, saxon9.jar xalan.jar etc..

Has anyone tried the server side approach or are there any other options to reduce the overall number of jar files within the par file.
