Actually you can....sort of.
from ATLS documentation.
SAVING TO THE MAP (if required)
All the settings you make in the ATLS will be saved to a Soup, so if you are running a Session that's all you need to do. In most cases you may name an asset to your choice and it will have no impact on its working, settings still being saved to a Soup. However, if you are saving purely for identification purposes, then you must avoid using the Control Characters. These characters are [ ] ( ).
If you want to save the settings you have made to a map, (if you are a Scenario script writer for example), then this may be done by saving the name of the asset as follows, using those Control Characters.
Open the Properties Dialogue Box of the ATLS asset you want to save and set it up as required. Then, look in the top left corner and you will see something like 'ATLS1[65,E,O]'.
This is an encoded representation of all the settings you have made to the asset. If you save the name of this asset EXACTLY as shown, the settings will be retained and recovered when you re-load the map. They will also work in a Scenario.
It’s important to keep the format exactly, including the square brackets and commas or it will either just not work, or may cause errors.
On occasions you may encounter the 'That Name Is Already In Use' message. If you do, don't save it but add '(A)' to the name you are saving. So you will save: 'ATLS 1[65,E,O](A)'. Use the letter (B), (C) etc., for subsequent clashes. The brackets are important.
If you want to change the 'saved name' or delete it, its always best to save the map and re-load afterwards. Otherwise errors may occur.
Remember, you don't need to save if you are just running normal Sessions.
(Special warning for the Controller asset. The generated name in this asset will get very long if you have lots of Routes and Phases. Note also that the Phase Timing durations are 'rounded' when saving to a map.)
