Yes! You can use our batch scaling tool to set or update the scale for multiple plans in your project. To do this on web, just hover your cursor over the thumbnails of each plan you wish to set the scale for and select the checkbox that appears on the thumbnail. If you want to select the whole set, just click the checkbox next to the plan folder they are housed in.
Once your plans are selected, click on the red "Actions" button at the top of the main Plans page and select "Edit Scale." You can then input the scale ratio that you want the plans to have.
