Can Autocad2013 create automatically blocks ?

Hello,

I've been working a while with AutoCad now but this week I received a task which I am not sure is not even possible to do.

I've been exporting drawnings from an other program into AutoCad2013 and all the objects in my drawning appear as loose objects in AutoCad.  Can AutoCad create automatically blocks from these loose objects ?

Example : I added a picture of a transformer in this message.  This object (2 circles, triangle and star) becomes all loose objects and is NOT one symbol anymore.  My question is, if it it is possible that Autocad can recognize these loose objects and create automatically blocks from them.  There are a lot of transformers in my drawnings and If I have to do it myself it will be loads of work.

Another thing they asked to do is working with correct European Symbols.  I should therefore change blocks in my drawnings into correct one's.  I believe when the wrong symbol is already a block it's more easy to change them.  I think I should just select all wrong blocks, edit them and then update them.
  But before this, I have to get blocks in my drawning ofcourse.

Can anyone help me or has idea's to solve it ?  Hopefully I've been clear enough.  English is not my native language.

Thanks in Advance.

Kind Regards,
