Bracket over two equations

Question

is there a way to join the two brackets at the end of the 4th and 5th equation together so it spans over these two equations and there is only one text?

\begin{align}
f(\beta_i^{r,c},\alpha_{r,c} \mid n_{r,i},t_{c,i},(\lambda_1,\lambda_2) \text{ or } \lambda) \propto \\
\times \prod_{i=1}^{P} \prod_{c=1}^C ({\theta_{c,i}})^{t_{c,i}} &\;\;\bigg] \textbf{Individualdaten}\\
\times \prod_{i=1}^{P} \prod_{r=1}^R \frac{1}{B(\alpha)} \prod_{c=1}^C (\beta_i^{r,c})^{\alpha^{r,c}-1} &\;\;\bigg] \textbf{Priori Distribution}\\
\times \prod_{r=1}^{R} \prod_{c=1}^C \frac{1}{\lambda_2 ^{\lambda_1} \Gamma(\lambda_1)} \alpha_{r,c}^{\lambda_1-1} exp(-\alpha_{r,c} \lambda_2) &\;\;\bigg] \textbf{Priori Distribution}\\
\text{or}\\
\times \prod_{r=1}^{R} \prod_{c=1}^C \lambda exp(-\lambda\alpha_{r,c} &\;\;\bigg] \textbf{Priori Distribution}\\
\text{with } B(\alpha)=\frac{\prod_{c'=1}^C \Gamma(\alpha_{rc'})}{\Gamma(\Sigma_{c'=1}^C\alpha_{r,c'})}
\end{align}
