Suggestion: Possibility to use multiple logos for 1 organisation

Suggestion: Possibility to use multiple logos for 1 organisation

I encounter a similar problem to the other question on the forum about Multi-Languages on Zoho Invoice, since I use several business names/identities (so at the moment need different organisations) but due to tax legalities (1 tax ID nr) I have to make sure that the invoice numbering is consecutive. That means every time reset the invoice numbering. Hardly makes it faster or easier than the old fashioned excell. 
Would be real handy if I could set my company logo per customer so that I have consecutive numbering but still can use the company name that is appropriate for that customer.
