Exon usage ratio

Is there any possibility to obtain exon usage ration for the data released in 2020 (i.e. a file like CCLE_RNAseq_ExonUsageRatio_20180929.gct but for the most recent release)?

We do not generate this data at the moment. We have been discussing about adding such a dataset to the portal, but the timeline of it is unclear at the moment.
