No, this is not possible. RouterOS only supports contiguous netmasks from the top.
However, you can use Address List to match several addresses with a single rule.
Only in very specific situations. In general this is not really useful.
You can fill an address list with the addresses you need, when desired you can use a loop in a script to add many entries to the list without having to type them all.
Or you can use a powerful text editor or shell to create the commandline commands and then paste them into a command window.
