download multiple output files in NR from bursting to my local library directly or from EPM automate

We have multiple excel outputs from bursting definition stored in NR library. but there is an option to download a single file at once. when we select multiple files, download option under actions will be greyed out and even if we export it, it will be a file resource type and we wont be able to open it as an excel sheet. is there any way to download multiple files at once from NR library or can we use any EPM automate command to do it?
