Update the girder slice command to give the ability to create multiple slices. Users would then be able to either rapidly click where they would like slices (eg. Holding ctlr+click allows for multiple slices to be created) or prompt the user for how many slices they would want and then have them just spaced evenly from the start point to where the user selects (they can move them later).
Current setup is cumbersome for creating multiple-slices; users have to create one. Wait. Select the new one. Hit plus. Create new one… repeat.
