Extract transcription from new version of ensembl GRCH37 issue

[gaom001]

From CAVA-1.2.3/ensembl_db -i transcripts.txt -e <version> -o custom_transcripts command, it will automaticlly pick up the GRCH38 version of ensembl transcripts (for example: 105, the latest version) . Is there any way to select GRCH37 or GRCH38?

Thanks!
