#933 (ok 4.5) manage multiple variable in bookmarked query

now i could only have a variable in a query, as example:

SELECT Name, Address FROM addresses WHERE 1 /* AND Name
LIKE '%[VARIABLE]%' */

but i cannot do this:

SELECT Name, Address FROM addresses WHERE 1 /* AND Name
LIKE '%[VARIABLE]%' AND age = [VARIABLE2]*/

it is most useful to have rhe possibility to easy
manage multiple variable query
