Please see Selectively Choose Products to Publish - Patch My PC Update Catalog for more details
To better support the upcoming third-party software update integration in Microsoft System Center Configuration Manager (SCCM), we are adding the ability to import our catalog per-product. The SCCM third-party software update catalogs feature will publish ALL updates in a catalog with metadata only. We want to give our customers the ability to add our catalog by-product if needed. This feature will allow you to selectively publish products to SCCM, and not have SCCM publish all 150+ Products.
