Apparently there is no global standard to classify the devices from a common nomeclature which could be used as search filter fields on the distributors websites - although they make it very similar in different vendors. If there were this, it could be possible to send a BOM with a format which could be interpreted by simple scripts on supplier's sites. When I worked on circuit design, I created extra fields in the device library that contained as many details as possible (Package, footprint, Voltage, Speed, etc...etc...) as well as vendor's stock link, and generally gathered into a few ones (eg, Digikey, Newark, etc ...). This is not exactly what you are looking for, but at least that way it would be possible for someone to look for similar parts if there were no longer stock there.
