You cannot put slide nor tab controls inside a portal row. But you can put a popover button that opens with buttons for these commands.
Then, with a bit of scripting, put a slide control in the pop over and put the portal inside the slide control. Put your buttons on a different panel of the slide control and give each panel an object name. Put a button inside your portal row that performs a script that does this:
captures the row number in a global variable so that a script can both reset the slide control to the portal's panel and reset the focus to the original row.
captures the primary key value of the portal record in a global variable so that the "command" buttons' scripts can use this value to be sure to affect the correct portal record.
Uses go to object to slide the slide control to the panel of command buttons.
