[Hilo] Is it possible to add up band numbers?

[Hilo] Is it possible to add up band numbers? Exampling: I want to use:
GSM 850MHz (0x0200) for voice;
WCDMA 1900MHz (0x0001) for upload;
WCDMA 2100MHz (0x0004) for download data.
Could I add them up like (0x0200 + 0x0001 + 0x0004 = 0x0205)?

Answer: No, in WCDMA network it is not possible to select one band for Upload and another one for Download.
