With a limited view of the sky, how do I chose my own alignment stars with the Synscan hand controller?

You can not choose you own stars. You have to choose from the list provided within the hand controller.
However, you can turn off the Alignment Star Filter to get a larger list of stars to choose from.
5.8 Alignment Star Filter
Not all combinations of alignment stars are good for a 2-star alignment or 3-star alignment. The SynScan hand controller uses a built-in advanced alignment star filter to show only the stars that are suitable to work with the 1st or 2nd alignment star(s), when asking the user to choose the 2nd or 3rd alignment star. This helps to improve the success rate of the alignment. Some advanced users or those who have limited sky visibility can turn on/off this advance filter with the following steps:
1. Access the menu “Setup \ Alignment Stars \ Adv. Filter” and press the ENTER key.
2. Use the scroll keys to choose “OFF” and then press the ENTER key to disable the filter.
3. Use the scroll keys to choose “ON” and then press the ENTER key to enable the filter.
Note: Even if the advanced filter function is turned off, the SynScan hand controller will still apply the following rules to generate the list of alignment stars: • The alignment star’s altitude must be above 15 degrees. • For an equatorial mount or mode, the alignment star’s declination must be between -75 and +75 degrees. • For an alt-azimuth mount or mode, the alignment star’s altitude must be below 75 degrees or within the altitude limits defined by the user (Section 5.6)
