Nope, sorry there is no group function for V1.

This is definitely a big missing area and working on grouping and object organization type methods is a big priority for version 2.0 .

For now you'll have to use stuff like a strategically placed window select to grab batches of things at once.

One quick note on the window select - if you click and drag a selection window starting from the left side and moving towards the right, you will get a selection rectangle with a solid outline - this type of selection window will only select items that are completely contained inside of it.

On the other hand, if you start on the right side and then drag towards the left, you will see a dashed outline window - this one will select anything that intersects the window in any way, not just stuff completely inside.

Sometimes strategic use of these selection windows can help to grab the right stuff pretty quickly.
