The normal *Alias* file is called 'Multichoice.xlsx' and it is, by default, co-located with your Instant Database records.
You can create a custom alias file, associate it with a particular document and that file will be used first in hunting for a matching alias.
There is not 'trick' to creating a custom alias file. Simply open an excel spreadsheet. Type in row 1 the alias you want to use (e.g., 'States', 'Courts', 'Attorney Names', etc; no quotes). Underneath each alias type the values you want the alias to represent. Save the spreadsheet as a normal spreadsheet. Save it either in the folder of the document(s) you will associate with the Custom Alias, or in the default *Alias* List folder. (You can actually save the list in any folder you wish, but when you assign a Custom Property, you must use the fully qualified name (drive letter and full path). We do not recommend this. If you move documents or the *Alias* list and forget to change the reference, the custom list will not be found.
To assign a Custom Alias list to the on-screen document:
1.Click File | Info
2.Click Properties (dropdown) | Advanced Properties
From the File | Info screen click the Properties dropdown (1) and then click Advanced Properties (2)
3.Complete the Custom information:
Click the Custom tab. Type 'Custom Alias' the 'Name' box (1).
Type the name of the Excel 'alias' spreadsheet in the 'Value' box (2).
Click Add (3) to save
The value can be just the spreadsheet name if it is stored in the same folder as the document or in the default Alias file folder. Otherwise, you must provide a fully qualified reference.
