It would nice if there is command line for batch translation in Linguist

For a large project having several language support where qt translations are being maintained in qph files, it would be nice when a change in large project takes place then translation can be done in batch through command line . As of now one will have to translate each ts file with the corresponding qph file content

something like this would be great:

cd project-dir
lupdate project.pro
batchuupdate << this is the missing step>>
lrelease
