However, I need to be able to specify a different color for each pushpin. Tried adding a color column with colors like red, green, blue - but Streets & Trips did not recognize. Is this possible in Streets and Trips?
There is a workaround to handle this now. It is a bit more of a hassle, but if you are dealing with large amounts of data, it's WAY better than doing it manually.
Separate your input data onto separate worksheets, then import each worksheet individually. They will each land in their own pushpin set. If you choose the "Legend and Overview" view, you can right click on each pushpin set, which will allow you to change the symbol for all of the members of the set at once. It also allows you to name that set, which defaults to workbook name plus an integer to keep it unique.
Alternatively, you can separate them into completely different workbooks, and name each file the same name you want their pushpin set to be named.
I hope this helps.
