I'm using the annotatr package and notice the build_annotations function gives different tx_id depending on whether its from hg19 or hg38. for example

build_annotations(genome = 'hg38', "hg38_basicgenes"  )
build_annotations(genome = 'hg19', "hg19_basicgenes"  )

hg38 looks like this.

where as hg19 looks like this.

is there anyway to get hg19 version to use ensembl id instead?

thanks.
