Help needed on Markets & Groups

[siva@xxxx]

Hello

I'm sure the question of Market and group has been brought up before. 
I tried searching the forum and gave up after a while. Could some 
kind soul out there help me with the following queries.

I have imported Metastock EOD data to Group 255. Now I want to assign 
the a particular counter to more than one group (i.e. from group 255 
to group 1 and group 4). Is this possible? When I assigned it from 
group 255 to group 1, a "move operation" takes place. I'm looking for 
a "copy operation" so that I can again assign the same counter to 
another group.

Secondly I would like to do the same operation using the Markets. 
Example a particular stock is listed in more than one Index, I would 
like to create a Market for each of this Index and assign the same 
stock to these various markets. Is this possible?

If so could you point me to some documentation on this or could you 
drop me a short note on this.

Thanks again
Regards
Siva
