[NTG-context] Indenting tables

[The Wizard]

All -
I am creating simple tables like this

\starttable[|l|l|l|l|]
\HL
\VL \bf Time Frame \VL \bf SAN A \VL \bf SAN B \VL \bf SAN C \VL \AR \HL
\VL 10pm to 6am - Backup \VL 1500 MB/s \VL 1500 MB/s \VL 1500 MB/s \VL 
\AR \HL
\VL 6am to 10pm – NBU Vaulting \VL \rightarrow \VL \rightarrow \VL 
4500MB/s \VL \AR \HL
\stoptable

The table is created fine, but I would like it to be "centered" in the 
surrounding text. The current table starts at the left page margin, 
rather than where the text starts. Is there a simple way to "indent" the 
left edge of the table to match the surrounding text? I have tried using 
\setuptables[align=middle], but it seems to have no effect.
