Automatically Add Rows To A Table Or Fields To A Query?

I am using Access 2007. I have an ODBC source feeding data into a table, to which I made a crosstab query that displays the useful data from that source. I need a way to add data(new field), using a form, that is a associated with the lines in the query. I've tried creating another table that uses the sample ID as the primary key, but I need it to automatically create a new row for each query line. Is there a way to do this, or better way to add data to a query. Examples are below.

The ODBC data looks something like this

SampleID PeakName Conc

sample1 THF 50
sample1 MEOH 10
sample1 propanol 25
sample1 butanol 15
sample2 THF 21
sample2 MEOH 15
sample2 propanol 17
sample2 butanol 23

I have the query look like:

SampleID THF MEOH propanol butanol (I need to be able to add a field here)
sample1 50 10 25 15
sample2 21 15 17 23

Linked table I created:

SampleID LIMS #
sample1 1234567
sample2 4567891

The problem is, for this table I have to manually select each sample ID. I want it to automatically add the sample IDs as new ones are querried.
