Did you know you can copy schedules in Revit from project to project? I don't mean the 'Insert from File' option under the insert ribbon, (this method is good for bulk copying) I mean literally CTRL+C / CTRL+V.
If you like the way a schedule looks, the parameters it uses including any custom project parameters, simply place the schedule on a sheet, then use the windows based 'copy' (CTRL+C). Open your new project and paste (CTRL+V) the schedule onto a new sheet. Visit your project parameters and you will also notice it has brought them along too! Easy.
One thing worth noting, this method will also copy over text styles, you will receive a warning if there is additional things, so read it to keep track of any unwanted standards, particularly from old projects.
