Multiple command for key shortcut

[og900aero]

Is it possible to assign multiple commands to a key shortcut?
Example I want to custom paste command: paste and deselect all. That is, I want to merge the two commands below:

{ keys = [ "p", "p" ], command = "paste_files" },
{ keys = [ "x" ], command = "select --all=true --deselect=true" },

I try:
{ keys = [ "p", "p" ], command = "paste_files", "select --all=true --deselect=true" }, but I get error message:
Failed to parse keymap config: expected an equals, found a right brace at line 78 column 87
