How to edit a Z/os dataset with Hex values in Zowe

I recently got to try IBM Zowe trial and got to play around MVS Explorer and JES explorer and other tools. I created a file in Z/os and tried to edit it in MVS explorer all looks good until I got some Hex or packed data in mainframe file. I don’t find an option to edit the files in Hex mode, which we normally do under ISPF by doing Hex ON. Is there an option to do it here?
I didn’t find a way to submit jobs from dataset or even from JES. Is that option available of not?

There is a submit from data set command in Zowe CLI (zowe jobs sub ds data.set.here), but not sure about Zowe desktop. In general, z/OSMF does not have good support of mixed encoding of binary fields, so you might not have too much luck trying to edit such files with Zowe.

Hello, please use FA. FILE AIS tools to edit in hex
