No. The allocation tags and partion tags are specified for the journal selected.
In the upcoming release of 2.17 you can select partion tags (financial, order, budget, others) and you can then create your custom allocation tags to post your costs/revenues to (project1, project2, fund1, fund2 etc) your specified allocation tag. From the details you will have a new column called tags where you can allocate the entry to your particular project or fund. You can post directly in the journal or from the target account.
