Please don't toppost.

As for your question, the -sub* options don't work with libass (maybe
someone should fix it), but with -ass-force-style you can force any
ASS style parameters, which are FontSize, PrimaryColour,
SecondaryColour, OutlineColour, BackColour, Bold, Italic, Underline,
StrikeOut, ScaleX, ScaleY, Spacing, Angle, BorderStyle, Outline,
Shadow, Alignment,  MarginL, MarginR, MarginV

The relevant parameter for you is Alignment, ASS specs say on it:
This sets how text is "justified" within the Left/Right onscreen
margins, and also the vertical placing. Values may be 1=Left,
2=Centered, 3=Right. Add 4 to the value for a "Toptitle". Add 8 to the
value for a "Midtitle".
eg. 5 = left-justified toptitle
